So you hooked the IMRC linkage back up to operate normally, just with no plates on the throttles?

If so, that means you are not getting the early timing & fuel ramp up.

You have more low end power just waiting for you... laugh

As for the surface area difference.

Surface Area of the Plates
The plates are .9mm wide x 34mm wide = 30.6 x 6 ports = 183.6mm total frontal area

The area of each 32mm Primary port is 804.3mm x 6 ports = 4825.8mm

The area of each 34mm Secondary port is 907.9mm x 6 ports = 5447.5mm

12 port total area: 10273.3mm

That's a 1.8% (maximum) increase in total area.
Zero increase in primary ports.
That's a 3.3% increase in the Secondary ports.

Surface Area of the Rods
Primary port - The rod diameter is 5mm x 32mm = 160mm x 6 ports = 960mm

Secondary Port - The rod diameter is 3.4mm x 34mm = 115.6mm x 6 ports = 693.6mm

That's a 16.1% (maximum) increase in total area. (minus plates = 18% overall)
That's a 19.8% increase in the Primary ports.
That's a 12.8% increase in the Secondary ports.
~Minus the plates = 16.1% increase overall.

So the numbers say the rods are over 9 tenths of the obstruction itself.

BTW - I measured the smallest part of the rod so the actual improvement would be slightly larger. Like ~1-3% Nothing noticeable.
